SPECIFICATION forming part of Letters Patent No. 497,187, dated May 9,1893.

' Application filed February 2, 1893. Serial No. 460,814. (No model.)

To aZZ whom it may concern:

Be it known that I, STEPHEN R. KIBBY, of the city, county, and State ofNew York, have invented a new and Improved VVindow-Sash Look, of whichthe following is a full, clear, and exact description.

My invention relates to improvements in sash locks such as are adaptedto lock window sashes; and the object of my invention is to produce avery strong, simple, and inexpensive lock which may be appliedconveniently to any window having the usual sliding sashes, which may bearranged so as to lock both sashes and hold them in a very securemanner, and which also is adapted to lock the lower sash shut, and lockthe upper sash so as to hold it partially open and permit ventilationand yet hold it in such a secure manner that it cannot be opened fartherfrom the outside of a window.

To these ends my invention consists in certain features of constructionand combinations 'of parts, as will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure l is a broken inside elevation of a Window provided with myimproved sash lock. Fig. 2 is an enlarged sectional plan on the line 2-2in Fig. 1. Fig. 3 is is a cent-ralvertical section of the lock on theline 3-3 in Fig, 2; and Fig.4 is a sectional plan on the line 4-4. inFig. 3.

The window is provided with the usual vertically sliding lower and uppersashes and 11 which are held to move in a frame 12 in the ordinary wayand are separated by the usual parting beads 13.

In the parting bead which is cut away for" the purpose, is secured, at apoint just above the top of the lower sash when the latter is closed, ahanger 14, which has its upper portion projected slightly backward sothat it may be secured firmly to the window frame, and at the bottom ofthe hangeris a flange 16 which also is adapted to abut with the windowframe. The hanger is held in place by screws 14 which project through itand into the frame. The thickness of the hanger is such that while itprojects somewhat from the parting bead, it will in no wise interferewith the sliding of the sashes.

At the bottom of the hanger is an outwardly extending flange 16 and atthe top is a similar but shorter flange 17, and these two flangessupport the vertical pintle 18 of the horizontally swinging bracket 19,which bracket has at the bottom a flange 20 through which the pintlepasses, and at the top a similar flange which also receives the pintleand which is projected inward to form a bolt 21, see Fig. 4-, whichswings in a recess 22 in the hanger 14. and is adapted to swing intoeither one of a vertical series of notches 23 which are produced in thestile of the upper sash 11 adja cent to the parting head. The bracket 19has on its outer face horizontal and parallel lugs 24 inwhich is held avertical screw 25, which at its lower end is threaded, as shown at 26,so as to turn in a threaded portion of the lower lug 24 and the screw isprovided with a slotted head 27 in which a screw driver, coin, or otherconvenient article may be inserted to turn the screw, and the screw isalso provided, near the top which projects well above the upper lug 24,with transverse holes 28 in which a nail or other article may beinserted in case the screw is to be turned down very firmly. The bracket19 is adapted to swing laterally so as to bring the screw above the wearplate 29 on the rail 30 of the lower sash, and this movement of thebracket throws the bolt 21 into one of the recesses 23 of the uppersash. It will be seen that by turning the screw 25 so as to make itimpinge firmly on the plate 29, the lower sash is firmly fastened andthe upper sash is also fastened at the same time. The bracket 19 is alsoadapted to move vertically to a certain extent on the pintle l8, andthis facilitates the operating of the bolt 21 in the notches 23, and theadjusting of the lock generally.

From the foregoing description, it will be readily seen that the lockmay be made to fasten the lower window sash firmly by simply swingingthe bracket above the sash and turning the screw if necessary, and itwill also be observed that bybringingone of the notches 23 into registrywith the bolt 21, the upper sash may be held securely and at the sametime partially open, as for instance in case ventilation is desired.

ICC

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A sash lock, comprising a swinging bracket held inthe parting bead of a window, and adapted to swing over the meeting railof the lower sash, and a vertically adjustable screw held in the freeend of the bracket and adapted to strike upon said sash rail,substantially as described.

2. The combination with the sliding window sashes, the upper of whichhas notches in its stile, of a swinging bracket held in the parting beadbetween the sashes and adapted to swing over the top of the lower sash,the said bracket having at its inner end a bolt to enter the notches ofthe upper sash, and a vertieally movable screw held in the free end ofthe bracket and adapted to strike the top of the lower sash,substantially as described.

3. The combination with the sliding sashes, the upper of which hasnotches in its stile,of a horizontally swinging and vertically movablebracket supported in the parting bead of the sashes and the brackethaving at its inner end a bolt to enter the notches in the upper sash,and a vertically movable screw held in the free end of the bracket andadapted to strike upon the top of the lower sash, substantially asdescribed.

STEPHEN R. KIRBY.
